Pierre is having trouble getting to sleep at night. Which practice is a way to improve his problem? watching calming TV before bed
getting out in the sunshine each morning
eating before bed to prevent hunger
going to bed at different times each night

getting out in the sunshine each morning

Explanation:

1: Watching TV right before bed disrupts your "internal clock". When you expose yourself to artificial light at that time, it can disrupt your circadian rhythm and melatonin levels, which confuses your brain. When your brain thinks it's still daytime at night, it can make going to sleep and staying asleep very difficult. Therefore, you should not watch TV (or electronics in general) before bed, even if it's calming.

2: Sunshine, unlike artificial light, regulates your circadian rhythm by telling your body when to increase and decrease your melatonin. Therefore, you should get out in the sunshine each morning.

3: Eating right before bed time can easily cause weight gain, and it can make you tired in the morning. You should not eat right before bed.

4: Going to bed at a consistent time is better than different times every day. One day you could sleep at 4:00 AM and another at 9:00 PM; this can negatively affect your body's metabolism and can put you at higher risk for chronic diseases. Therefore, you should not go to bed at different times each night.
